I actually don't know, what a preset file is, and I also do not have a 
HDSP, so I guess that this won't work with a RME 9636 card anyway, isn't 
it? Meanwhile I made a kind of proceeding with setting 'Channel thru' to 
true for channel 0 and leaving Passthru 'false'. And: Only if I keep 
qjackctl up and running while restoring that configuration to the card, 
then the sound comes through cleanly on the left side aka AEB-O's jack 
1. Channel 0 and 1 are also my main outputs on the AEB-0 connector, and 
if I start ardour rolling, I cannot hear the left track anymore.....only 
the monitor signal, urrrggh. But I think, I start to to understand:

1. Channel thru makes this channels in _and_ output only useable for the 
monitor signal, it doesn't automagically mix with what is coming from 
another source.
2. To get a no latency mix of both for monitoring while recording, I 
mean the monitor signal and the tracks, I still need an external analog 
mixer,
or I have the monitor on the left and everything else on the other 
side...hmm not really exciting.

Agreed?
